In the absence of evidence to support our claims we are required to include an imo, I am told.
I think you will find that if you review what I wrote carefully, I made no unsubstantiated claims, merely posed a couple of questions and was only seeking your opinion - I take your unnecessary request for evidence as an attempt at deflection.
Here's what I wrote again:
Does it not stand to reason that a dog trained to look for evidence in a crime scene should also be trained not to pick up (and contaminate) potential evidence in his mouth? Say Eddie had previously been rootling around some old cadaver, and then snuffled his way around a crime scene looking for evidence. Any risk of cross contamination there, in your opinion?
You can of course answer: no it does not stand to reason that a dog should be trained not to contaminate a crime scene, and no risk of cross-contamination from the dog, and that will be the end of it.
